MANUFACTURING CATHODE MATERIAL, CATHODE, AND LITHIUM ION BATTERY |
| 摘要 |
A cathode material which does not easily deteriorate when used in batteries, a method for producing cathode materials, a cathode, and a lithium ion battery are provided. A cathode material including a cathode active material, in which the cathode active material is expressed by Li1+xAyDzPO4 (here, A represents one or more metal elements selected from the group consisting of Co, Mn, Ni, Fe, Cu, and Cr, D represents one or more metal elements selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, Y, and rare earth elements, 0<x<1, 0<y<1, 0≦z<1.5, and 0.9<y+z≦1), and, in thermogravimetric analysis in an inert gas atmosphere, when a temperature is increased in a temperature range from 100° C. to 300° C. at a temperature-increase rate of 10° C./minute, a weight loss ratio in the temperature range is 0.3% by weight or less. |

1. A cathode material including a cathode active material,
wherein the cathode active material is expressed by Li1+xAyDzPO4, wherein A represents one or more metal elements selected from the group consisting of Co, Mn, Ni, Fe, Cu, and Cr, D represents one or more metal elements selected from the group consisting of Mg, Ca, Sr, Ba, Ti, Zn, B, Al, Ga, In, Si, Ge, Sc, Y, and rare earth elements, 0<x<1, 0<y<1, 0≦z<1.5, and 0.9<y+z≦1, and the cathode material has a weight loss ratio of 0.3% by weight or less, wherein the weight loss ratio is measured in a thermogravimetric analysis, which is carried out in an inert gas atmosphere; and a temperature is kept at 100° C. for 30 minutes, increased from 100° C. to 300° C. at a temperature-increase rate of 10° C./minute and then kept at 300° C. for 30 minutes. |
